The 'fun-sized' trolleys are designed to help keep children engaged while mums and dads do the weekly grocery shop.

It comes after the budget supermarket tried out the new items in its stores in London and Oakham, East Midlands.

Lidl UK’s Commercial Director, Ryan McDonnell, says: “We’re constantly looking for new ways to make shopping more fun and engaging for kids. We’re keen to help parents build their children’s understanding of what they eat, and we hope that our new Fun Size Trolleys will encourage kids to play a bigger part in the family shop.”

The trolleys are named after Lidl’s Oaklands Fun Size food range, which includes mini versions of fruit and vegetable varieties.
